Reprogramming Passenger Door Module
Owners of some 2003 Chevrolet and GMC full-size pickups and utilities, Cadillac Escalade models and Hummer H2 may have concerns that the RKE key fob does not function, the front passenger door power window, lock, mirror and heated seat are inoperative.
The Door Lock and Side Window Switch contains a microprocessor called the Passenger Door Module (PDM). The condition and repair procedure involve the PDM.
- Those built before 01/03 -- refer to Bulletin 03-08-52-001C.
- Those built during 01/03 -- refer to Customer Satisfaction Bulletin 03-011.
- Those built 02/03 or later -- refer to published Service Information for the symptom experienced by the customer.
Instead of replacing the Door Lock and Side Window Switch, you can now refresh and reprogram the PDM using your Tech 2.
TIP: Your Tech 2 must contain software 23.001 (CD 3) or newer, released March 8. If it does not, you must download this software before proceeding.
And once you have identified the correct bulletin, you MUST perform the procedures described in it, in the order given, and do not skip any steps.
